Gattis (sports hernia) is expected to begin his rehab assignment at Double-A Corpus Christi on Thursday, Jake Kaplan of the Houston Chronicle reports.

EDGE Analysis

Gattis is set to join the Astros' Double-A affiliate Tuesday to resume working out. Provided that he gets through conditioning with no issues, he'' draw into the lineup Thursday to get his rehab assignment started. It's unclear how long the Astros will want him down at Double-A, but given Gattis' lengthy absence due to sports hernia surgery, it could stretch out for several games to get his bat back up to speed.
